What is the difference between HSL and HSB/HSV?
HSL (Hue, Saturation, Lightness) and HSB/HSV (Hue, Saturation, Brightness/Value) use the same Hue axis but differ in the third component. CSS uses HSL. HSB/HSV is common in design tools like Photoshop and Figma.
How do I convert CMYK for print?
CMYK values are percentages. HEX and RGB are screen (RGB) values. Converting between them requires a colour profile; this tool does a direct mathematical conversion which is accurate for most web-to-print approximations.
Can I use the native color picker?
Yes — click the swatch to open the browser's native color picker. The chosen color immediately updates all output formats.
